Yes three strings. This one is tuned gdg. I’ve seen some with a pair of high g strings (so four strings) but not actually heard them. the fret pattern for this comes from plans that I got from Michael J. King, a luthier in England. The positioning is very anoyingly precise. I’ll be building king’s rounded body version next. It’s a proper instrument.
